Abstract

PURPOSE: To prepare a stable organic bromide, economically, in high purity and yield, suppressing the side reactions, by brominating an unsaturated organic compound in the presence of a solution of an inorganic salt at about room temperature.
CONSTITUTION: An unsaturated organic compound having a C=C bond or C≡C bond, is brominated with a brominating agent in the presence of a solution of an inorganic salt obtained by dissolving a halide of an alkali metal, strontium, etc., ammonium bromide, ammonium chloride, ammonium sulfate, etc., in water or an organic solvent. The bromination reaction is pref. carried out at ≤50°C. After the reaction, the inorganic salt solution can be recovered and reused by liquid-liquid separation followed by neutrallization. The brominating agent is pref. obtained by dissolving bromine in the above organic salt solution.
